    On the Formation of Planets in the Milky Way’s Thick Disk by Tim Hallatt, Eve J. Lee

    Published 2025-01-01
    “…One key difference between the two stellar populations is the time at which they emerged: thick-disk stars are the likely product of cosmic noon (redshift z ∼ 2), an era characterized by high star formation rate, massive and dense molecular clouds, and strong supersonic turbulence. …”

    Galaxy Evolution in a Pilot Survey up to z=1 and CDM Halos by E. Giraud, J. Melnick, Q.-S. Gu, H. Quintana, F. Selman, I. Toledo, P. Zelaya

    Published 2011-01-01
    “…We revisit the question of downsizing in emission-line galaxies between z=0.9 and z=0.45 in our pencil-beam and find the following results: strong star formation in emission line galaxies, aging in emission line galaxies, and aging in absorption systems, are shifting from bright to faint systems as cosmological time increases. Each redshift bin is repopulated in new starbursts. Therefore at redshifts z⩽1 galaxy formation is downsizing both in luminosity and number density. …”
